Prosecutors say Giuca, then a skinny 20-year-old, was a leader of a self-styled gang called the Ghetto Mafia. At trial, prosecutors said Fisher was targeted for showing "disrespect" by sitting on a table in Giuca's house.
Giuca ordered another gang member "to go show that guy what's up," then gave the shooter a .22-caliber handgun, prosecutors said. At dawn, police responding to a report of gunshots found Fisher's body shot five times and dumped on a sidewalk.
It took more than a year for police to arrest the shooter. Giuca was taken into custody one month later after authorities secured witnesses who linked him to the crime.
A jury deliberated only two hours before convicting Giuca of second-degree murder in 2005. He and the gunman were sentenced to 25 years to life in prison by a judge who told them that because the killing was callous, "my sentence will be callous."
Lawyers for Giuliano and Allo refused requests to speak to their clients. But court papers — along with a piece in Vanity Fair magazine and an article in The New York Times based on interviews with Giuliano and Allo — detail a story of despair and deception.
Giuliano, 47, says she was driven by the belief her son was set up by authorities and vilified in the press.
"My main concern was that John got a fair trial," she said.
Said Allo: "I understand her motivation, but that's not right."
Allo's lawyer declined to discuss Giuliano's tactics. But her lawyer said under state law, she "had a right to record those conversations."
"Ultimately, the only person who acted inappropriately was Mr. Allo," Glaser said.
By Giuliano's own account, her son's conviction nearly gave her a nervous breakdown. In 2006, she hatched a plan to begin spying on jurors to see if she could uncover any misconduct.
She eventually zeroed in on Allo, a construction worker with a shaved head living in the Bensonhurst section of Brooklyn. She tailed him for months, once even wearing a head scarf as a disguise.
